We report the spectroscopic observations of the following transients from the SALVATION project (ATel #13952). They were flagged from the ZTF public alert stream by the ANTARES alert-broker. The spectra were obtained on 2021 August 5 UT with the Kast double spectrograph on the Shane 3-m telescope at Lick Observatory.
